Neighbors said the situation unfolded just after 3 p.m. when Jack Honacher, 61, got into an argument with two people on his front lawn on Northwest Seventh Court.

"The kid came onto his lawn and said, 'Go ahead, get your gun,'" said John Hinchui, a neighbor who saw the incident. "He was the one who was screaming."

"A young lady ran down and said, 'He got a gun,'" neighbor Leland Campbell said. "That's when all the chaos broke loose."

Police said when the first officers arrived, Honacher told them they would have to shoot him, and he then went inside his house with his gun.

Honacher then told police he would only speak to them if they came to his front door, investigators said.

Police chose to call a SWAT team instead, which surrounded the house and placed snipers in position.

Negotiators tried talking to Honacher for hours, but they said he never responded. They said he was posting on his Facebook page instead.

The initial post said he was "under siege" by the Boynton Beach police. Most of his posts were directed at the police, saying things like, "Come back with a warrant," and, "Go home. Take a few days off. Call in sick."

About three hours into the standoff, police fired tear gas into Honacher's home and then went in and brought him out in handcuffs.
